I'm still not clear how is Oneplus nord able to do 4K60 recording with the front camera? This is because there is a technical limitation of the SD765G ISP where it is unable to do 4K60. Only SD845 and above can do 4K60..
Another question is if it was able to do 4K60 with the front camera, why did it not extend to the rear camera as well? That would have been revolutionary, despite the chip not supporting it.
